Those blades are from a Super Fan made in Freeport, Illinois beginning in 1934 or 1935. The Super Fan is very close to the Marathon in design but it uses a Wagner motor. Terry bought one of a pair that I found near Madison. Stover Manufacturing of Freeport also sold circulators at the same time although I have yet to see one in the flesh.

Here is a Marathon four blade Super Air Screws model for comparison. The blades are a bit larger than the Super Fan. I find it interesting how similar the names, cage design, and blade design are between these two different brands.

I believe you have a good idea. A new fan model: Daisy Blade Kreig McClain. That would not only move some serious amounts of air but also look just too dangerous.

Thanks for the background information about those fans plus the pictures. I've never seen a carrying handle on a Super Air Screw. Those models are impressive fans. I'm anxious to get my Super Fan restoration completed. When I get that blade I will polish it and then get the fan back together.

Super-Fan Mfg. Co. is shown in Google books as snippet views(a book peek-a-boo) in ......32....34...38.

My impression....the Freeport Super-Fan and Wausau Marathon with those funky 4 wing blades preceeded the James Funk patented circulator blade. http://www.google.com/patents/about?id=pAVtAAAAEBAJ&dq=D97601 To support this, Stefan's Marathon motor is not held within Marathon's patented aluminum motor support. Just a thought.

I would bet your sweet bippy both Marathon and Super-Fan outsourced their forged blades and cages from Manufacturers in the windy city?? I don't recall running into that 4 wing blade in patent scans of Chicago. Doubt there is one?

From my understanding Funk had issues with alcoholism, and may of sold his blade patents for a song. I have seen his blades on the open market in books down the road of 40s-50s? To think that the present day Airmaster was, or is STILL using this one........http://www.google.com/patents/about?id=fl9xAAAAEBAJ&dq=D113347 If memory serves me right Funk passed of a failed liver at the age of 48.
